BURGLAR-PROOF SAFE.

SPECIFICATION forming part of Letters Patent No. 261,538, dated July 25,1882.

w Application tiled Apiil 2, 1 'T!l. Renewed December 220, IFFI..\lodt:l.)

To all whom it may concern Be it known that 1, WILLIAM ConLtss, ot' thecity and county of Providence, in the State of l-thode Island, haveinvented certain new and useful Improvements in Burglar-Proof Safes; andI do hereby declare that. the following is a full, clear, amt exactdescription t h root.

l. have in Letters Patent issued tome April 30,1872, described aspherical form of safe with provisionsi'or properly operating the door'thereot', which possesses marked advantages.

It has long been proposed to toughen and strengthen rcctangularsat'esbybars oi'wrought 1 iron or steel inclosed within the casting. l

have discovered and practically wrought out a modc-ot'fipplyiug'analogous bars in my spherical sai'e, so as torealize tho-ad 'antagosdue thereto without interfering with the pecu- 2o liar qualities of thespherical sale, and so as to give increased strength due to alirmuniting of the bars together before their introduction into themold. I have also made a complete union between the cast and wroughtmetals, so that the sale utilizes for that reason the strength of thetibrous metal more fully than in ordinary sales. 7

The accompanying drawings term a part of .this specilication, andrepresent. what 1 con- 0 sider the best means ot carrying out theinvention.

The interior or hollowside is n-escnted toward ti: i eve. l i 2 i. 1 3 s partial section,showing the basket without the series of internal bars.

The positions merely of the others are shown by dotted circles.Fig. 3 is a partial section at right angles to'l ig. L, and showing thebasket with its internal parts fully in place. These parts, except thestout uniting-bar, may be attached 5 by small wires. 1 have indicated noattempt to unite the parts of, the basket strongly except by the single.main hoop or uniting piece. Figs. 4- and-5 show n'iyc orrespondingstronglynnited frame for what I term the front ring.

.l adopt; the general construction shown in the modification of myoriginal patent dated March 2."), 1873..

A is the. main body, formed with an internal screw-thread, a.

his the door, which will be understood as equipped with the mechanismshown in the. patent last rel'erred to, or otherwise adaptedl'orconveuientoperation and for socurimg when properly closed.

The exteriors of all the parts A, U, and Dare of some hard materialwhich may be cast, and which is adapted to resist driiling-iron castin achill, i'rankliuite, cast-steel, semi-steel, or the like. This castmetal M is formed in a suitable mold, and ilows around and covers andunites strongly with the interior basket-work.

The baskct-\vork in each instance contains two sets oi pieces, m in,strongly united together. They may boot any wrought-iron or any steelwhich will endure high temperature;

but I will describe them as soi't and t ugh i'ennsylvania iron. Theyareproperlycurved casting, and when placed in the moldarc held in theirproper central positions in the castiugsbyanchors. (Xotrepresentcih)Thebasket m m is tinned bci'ore it is placed in the mold, and on beingsurrounded by the melted cast metal the high temperature 01' the castmetal is imparted to thewrought metal and the tin serves'as a ilux,enabling the whole to unite.

In Figs. 1, 2, and 3 there is an additional set of parts, nah-whichliejustwithin theparts Lil m and are'lightly attached to the latter bysmall wires or the like. Such slight fastenings are only intended toserve the temporary purpose of holding the parts in the proper positionsuntil the melted metal M can flow perfectly around them. After that thehigh temperature will ordinarily destroy the slight wire fastenings (notshown) which hold the parts at and m together; but before this iscompleted the cast metal M has sulliciently hardened to prevent theparts irom becoming displaced.

' he parts m m are stronglunited of themselves by means which hold themforcibly together independently of or additionally to the holding due tothe cast metal M.- The parton is in; the form of astouthoop punched ordrilled and receiving theparts m in suchholes. After all are insertedthe stouthoop m is compressed tightly upon the parts m by blows of ahammer or otherwise, so that it shall slightly indent the material m andhold the parts strongly engaged.

In Figs. 1, 2, 3, 4, and 5 the same mode of The other end is spread, asindicated, to anchor strongly in the cast metal M additional to theadhesion due to the heated union with flux.

In Figs. 7 and .8 there are stout hoops corresponding to m, and a seriesof four stout transverse straps with rivets corresponding to an. ,Theselatter take hold rivetwise of the parts m and hold the whole in astronglyunitcd basket, :ulditional'to the hold insured by the envelopingcast metal M and the welding or adhesion of the latter to the surfaces.

The basket m m is carefully proportioned ,to the space itis to fill, andis held in such position that its parts will be completely embedded. Itcontributes to the burglar-proof qualities of the safe by being softerthan the surrounding metal, tending by well-known laws to break anydrill which may touch it. It also contributes to the strength by holdingthe arts reliably together after the casting hasbeen fractured by anyviolence.

The riveting or analogous strong fastening of the parts m m togethercontributes to'thc strength of the completed structure and aids inholding the bars at the previous stages with the exactnessrequircd forspherical work.

I have experimented on a large scale, tin- As a preparation for thetinning, I first treat the surfaces of the basket with dilute nitricacid and afterward with dilute muriatic acid in which zinc has beenimmersed. Then the, tinning may be effected by a simple plunging in thebath-of melted tin.

It will be observed that where the main body ring, 0, there are twolayers of the wrought iron basket-work--one layer in each part of thesafe. I attach much importance to this pecuincreased securityto thispart of the structure. In its absence the outer part might possibly bechipped awayor the inner part might be broken across.

The spawling off or crumbling away from the exterior is one of the modesby which a burglar having plenty of time and tools would attack thesafe. The basket-work extending over the threaded joint 0 is importantin preventing that. y

The rending apart of the front ring in the driven into the latter fromthe exterior is anconditioned would attempt an entrance. Thebasket-workextending under the scrcw-th read 0 prevents this. r

I claim as my invention- 1.. A wrought-iron basket-work composed of thestout ring m, perforated as shown, in com bination' with the curved ribsor transverse strongly secured therein, adapted to serve in a sphericalsafe, and to contribute to the strength thereof by their directconnection, as herein specified.

2. The spherical safe described, of wrought and cast metal, the wroughtmetal being composed of two parts orsets of parts, the part am beingperforated and receiving the parts at in the holes thereof, and stronglysecured togetherin addition to the junction effected by the cast metal,substantially as herein specified.

3. In aspherical safe,thc independent hoops or rings m of wrought metal,in combination with the basket m m, ofstrongly-joined pieces, and thewhole enveloped in a harder cast metal, M, as herein specified.
